Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and, therefore, do not include all information and notes normally provided in audited financial statements. The accounting policies are described in the “Notes to Consolidated Financial Statements” in the Annual Report on Form 10-K for the 2026 fiscal year filed with the SEC on March 23, 2026 (the Form 10-K) and updated, as necessary, in this Form 10-Q. The year-end condensed consolidated balance sheet data presented for comparative purposes was derived from audited financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and adjustments) considered necessary for a fair statement have been included. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for any other interim period or for a full fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Form 10-K.

Basis of Consolidation

The Company’s fiscal year ends on January 31. The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in conformity with U.S. GAAP. All intercompany transactions and balances have been eliminated upon consolidation.

Concentration of Risk

The Company’s products are manufactured, assembled and tested by third-party contractors located primarily in Asia. The Company does not have long-term agreements with these contractors. A significant disruption in the operations of one or more of these contractors would impact the production of the Company’s products which could have a material adverse effect on its business, financial condition and results of operations.

A substantial portion of the Company’s revenue is derived from sales through one of its distributors, WT Microelectronics Co., Ltd., formerly Wintech Microelectronics Co., Ltd., or WT, which serves as its non-exclusive sales representative and fulfillment partner in Asia other than Japan. Termination of the relationship with WT could result in a temporary or permanent loss of revenue. Furthermore, any credit issues from WT could impair its ability to make timely payment to the Company. See Note 15 for additional information regarding revenue and credit concentration with WT.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketable debt securities and accounts receivable. The Company maintains its cash primarily in checking accounts with reputable financial institutions. Cash deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The Company has not experienced any losses on deposits of its cash. In order to limit the exposure of each investment, the cash equivalents and marketable debt securities consist primarily of money market funds, fixed deposits, commercial paper, corporate bonds, asset-backed securities and U.S. government securities which management assesses to be highly liquid. The Company does not hold or issue financial instruments for trading purposes.

The Company performs ongoing credit evaluation of its customers and adjusts credit limits based upon payment history and customers’ credit worthiness. The Company regularly monitors collections and payments from its customers.

Restricted Cash

The restricted cash primarily consists of a Letter of Credit of approximately $0.4 million with a financial institution as collateral for the security deposit on its office lease located in Santa Clara, California, as well as those amounts required to be set aside to secure certain transactions in a foreign entity. The following table presents cash, cash equivalents and restricted cash reported on the condensed consolidated balance sheets, and the totals are presented on the condensed consolidated statements of cash flows:

Recent Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This new guidance requires public entities to provide disaggregated disclosures, in the notes to the financial statements, of certain categories of expenses that are included in expense line items on the face of the income statement. The ASU may be applied prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027. Early adoption is permitted. The Company expects to adopt this new guidance for its fiscal period ending January 31, 2028. The Company expects that such adoption will only have an impact on its financial disclosures and does not believe it will have a material impact on its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This new guidance simplifies the estimation of credit losses on current accounts receivable and current contract assets arising from transactions accounted for under Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, and allows all entities to elect a practical expedient to assume that the current conditions as of the balance sheet date will remain unchanged for the remaining life of the asset when developing a reasonable and supportable forecast as part of estimating expected credit losses on these assets. The new guidance is effective for fiscal years beginning after December 15, 2025, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted this new guidance and elected the practical expedient in its first quarter of fiscal year 2027. The adoption did not result in a material impact on its consolidated financial statements and disclosures.
